There are a few different ways BioWare could have reacted to their game, Mass Effect 2, being accidentally shipped (http://www.rockpapershotgun.com/2012/11/13/codbloopers-a-mass-production-error/) in boxes of Call Of Duty: Black Ops 2. It‚??s looking like they‚??ve picked the best possible one. Rather than getting upset, the studio is seeing it as splendid marketing, a promotional opportunity, and explaining to those who‚??ve received a copy of their game that ‚??the universe thinks you should be playing Mass Effect right now.‚?? They‚??ve gone so far as to create a competition for those with the wrong disc.
